Patented Dec. 26, 1933 UNITED; tSTA TEES {PATENT A or ies "r FTINGBUTTfON v Wilfred B. Mathew on; North Weymouth, Mass, assignor'toUnitedMattress Machinery Com pany, Quincy, Mass; a ,corporaticn of Maine- Application February 28,1933. serial'Natsasts GLClaimsl (01. 24-40)Thisinvention relates to-tufting buttons such as are used in tuftingmattresses, upholstery and the like and has for its generalobject-toprovide a novel tufting button which can be easily. applied I 5to a loop of tufting cord which has been previously inserted in themattress or other article to be tufted, and which is so constructed thatit will retain its attachment to the loop when in use.

A tufting button embodying the present in- IQ vention is of the usualtype which is made; of

sheet material and presents separated front and back portions that areunited along the peripheral edge of the button. The back of the buttonis provided with two cordor tape-receiving apertures through which theloop of tufting cord or tufting tape passes when the button is attachedthereto. These two apertures are connected by an S-shaped slot and theback portion of the button is so formedas to facilitate the entrance ofthe loop of tufting cord into said apertures through said S-shaped slotand to prevent the cord or tape from being dethreaded from saidapertures when the button is in use.

In order to give an understanding of the invention I have illustrated inthe drawing a selected embodiment thereof which will now be describedafter which the novel features will be pointed out in the appendedclaims.

Fig. 1 is a sectional view through a tufting button embodying myinvention showing it applied to a mattress, the section through thebutton being on the line x:c, Fig. 2;

Fig. 2 is a backside view of the bottom;

Fig. 3 is an edge view thereof looking from th left Fig. 2;

Fig. 4 is an edge view of the button looking from the top, Fig. 2.

In the drawing 1 indicates a fragmentary portion of a mattress which hasthe usual ticking 2 and the filling 3.

The tufting button embodying my inventionis indicated generally at 4. Itis of the type which presents a front portion 5 and a back portion 6,both of sheet material, said front portion and .45- back portion beingfastened together in any usual way around the periphery of the button asindicated at 7. The back 6 of the button is provided with two apertures8 to receive the loop 9 of the tufting cord or tape 10. These apertures8 are in the back 6 and extends between the apertures in a diagonaldirection, each end of the slot being curved as shown at 12 and enteringone of the apertures in a tangential direction. The slot which is thusformed has a general 8 shape and tween'each horn portion and the back ofthe connected by a threading slot 11 which is formed theends.13;of;.,the slot enterthe two apertures on the outer sides thereof,that is, on the sides thereof which are adjacent the periphery of thebutton.i--The aperture'sB are-thus located onthe inner sides of theends'l3 of the slot. This con- 0;

'struction provides the two horn-shaped portions edge 15 of eachhorn-shaped portion is directed outwardly from the back of the button asshown best in Figs. 3 and 4. With this construction there will be aconverging throat 26 formed bebutton through which aloop of tufting cordcan be readily entered into the slot 11 and when. the loophas been onceentered into. the slot it can, by proper manipulation of the button, beworked through the slot so that it will be carriedinto and through thetwo apertures 8 as shown in Figs. 1 and 2. v I

Each horn portion 14 is also so shaped as to provide a constructionwhich will prevent dethreading of the apertures'Q. Each horn portion 14is so deformed as to present not only the outwardly-directed curved edge15 but also so that the point 16 will be'directed inwardly and will belocated withini'he confines of the back of the button. Suchinwardly-directed points 16 are located at the points where theslotenters the apertures and because of their shape they serve to retain theloop 9 in the apertures 8 and so I to prevent said loop from working outof the S-shaped slot through which a prepared loop of tufting cord maybeentered into said apertures.

2. A tufting button having in its back two cord-receiving apertureswhich are connected by an S-shaped slot through which a prepared loop oftufting cord may be entered into said apertures, said slot enteringaperture on the side thereof adjacent the periphery of the button.

3. A tufting button having in its back two cord-receiving apertureswhich are connected by an S-shaped slot through which a prepared loop oftufting cord may be entered into said apertures, said slot entering eachaperture tangentially on the side thereof adjacent the periphery of thebutton.

4. A tufting button having in its back two cord-receiving apertureswhich are connected by an S-shaped slot through which a prepared loop oftufting cord may be entered into said apertures, said slot entering eachaperture on the side thereof adjacent the periphery of the button,whereby the back of the button is formed with a horn-shaped portionbetween each aperture and the curved portion of the slot entering saidaperture, the convexly-curved edge of each hornshaped portion being bentoutwardly to provide a throat through which the loop of cord may beentered into the slot.

r 5. A tufting button having in its back two cord-receiving apertureswhich are connected by an S-shaped slot through which a prepared loop oftufting cord may be entered into said apertures, said slot entering eachaperture on the side thereof adjacent the periphery of the button,whereby the back of the button is formed with a horn-shaped portionbetween each aperture and the curved portion of the slot entering saidaperture, the convexly-curve d edge of each horn-shaped portion beingbent outwardly to provide a throat through which the loop of cord may beentered into the slot, and the point of each horn-shaped portion beingbent inwardly to retain the loop in the aperture.

6; A tufting button having in its back two cord-receiving apertureswhich are connected by an S-shaped slot through which a prepared loop oftufting cord may be entered into said apertures, said slot entering eachaperture on the side thereof adjacent the periphery of the button, andthe adjacent marginal edges of the apertures being bent outwardly topresent a rounded seat for the loop if tufting cord.
